Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADC0820CCWM is determined by strict alignment with the following electrical and mechanical parameters:

Critical Matching Parameters:

• Resolution: 8 bits
• Number of inputs: 1
• Input type: Pseudo-differential or single-ended capability
• Architecture: Flash
• Data interface: Parallel
• Configuration: S/H-ADC with 1:1 ratio
• Reference type: External
• Supply voltage ranges: 4.5V ~ 8V (both analog and digital)
• Operating temperature: 0°C ~ 70°C
• Package: 20-SOIC form factor
• Mounting: Surface mount

All identified substitute parts meet these core electrical and mechanical requirements, enabling direct functional replacement in applications designed for the ADC0820CCWM.

Engineering Selection Recommendations

For Active Production Designs:

The TLC0820ACDW, ADC0820CCM+, and ADC0820CCM+T are all active components suitable for new designs. These parts offer ROHS3 compliance and improved moisture sensitivity ratings (MSL 1, Unlimited) compared to the obsolete ADC0820CCWM (MSL 2A, 4 Weeks). The TLC0820ACDW is manufactured by Texas Instruments and maintains the original design lineage. The ADC0820CCM+ and ADC0820CCM+T variants from Analog Devices Inc./Maxim Integrated provide equivalent electrical performance with enhanced environmental compliance.

For Legacy System Support:

The ADC0820CCWM/NOPB maintains active status and provides direct compatibility with existing designs. This part is available in bulk packaging and represents the closest functional equivalent to the original ADC0820CCWM.

Packaging Considerations:

Selection between tube (TLC0820ACDW, ADC0820CCM+) and tape & reel (ADC0820CCM+T) packaging depends on production volume and assembly requirements. Bulk packaging (ADC0820CCWM/NOPB) is available for lower-volume applications.

Frequently Asked Questions (FAQ)

Q: Can the TLC0820ACDW replace the ADC0820CCWM in existing designs?

A: Yes. The TLC0820ACDW meets all electrical and mechanical parameters required for direct substitution. Both components feature 8-bit flash architecture, single input, parallel data interface, external reference configuration, and identical supply voltage ranges (4.5V ~ 8V). The 20-SOIC package and surface mount configuration are identical. The primary difference is that TLC0820ACDW is active and ROHS3 compliant, whereas ADC0820CCWM is obsolete.

Q: What is the difference between ADC0820CCM+ and ADC0820CCM+T?

A: Both parts are electrically identical 8-bit flash ADCs from Analog Devices Inc./Maxim Integrated with matching specifications. The difference is packaging: ADC0820CCM+ is supplied in tube format, while ADC0820CCM+T is supplied in tape & reel format. Selection depends on assembly process requirements and production volume.

Q: Are all substitute parts RoHS compliant?

A: The TLC0820ACDW, ADC0820CCM+, and ADC0820CCM+T are ROHS3 compliant. The ADC0820CCWM/NOPB RoHS status is not specified in available documentation. The original ADC0820CCWM is RoHS non-compliant.

Q: Do substitute parts require circuit modifications?

A: No. All substitute parts maintain identical electrical specifications including input type (pseudo-differential/single-ended), architecture (flash), data interface (parallel), reference type (external), and supply voltage ranges. No circuit modifications are required for functional replacement.

Q: What is the significance of MSL rating differences?

A: The original ADC0820CCWM has MSL 2A (4 weeks), indicating moisture sensitivity requiring controlled storage conditions. Substitute parts TLC0820ACDW, ADC0820CCM+, and ADC0820CCM+T have MSL 1 (Unlimited), indicating superior moisture resistance and simplified storage requirements.

Q: Is the ADC0820CCWM/NOPB suitable for new designs?

A: The ADC0820CCWM/NOPB is active and functionally equivalent to the original part. However, for new designs, the TLC0820ACDW or ADC0820CCM+ variants are preferred due to ROHS3 compliance and improved environmental ratings.
